MILK-STRAINER.

Application filed November 18, 1915.

To all whom it may concern: H

Be it known that 1, WILLIAM E. Jun KINS, a citizen of the Unitec States, residin at l Varwick, in the county of Orange and btate of New York, have invented certain new and useful lnlproven'ients in Milk-Strainers, of which the following is a specification.

My invention relates to an improvement in milk-strainers, and the object is to pro vide an article of this description to fit the top of an ordinary milk-can, and one of the advantageous features is that the straining medium can be easily and quickly removed and replaced so that it can be kept clean at all times.

The invention consists in a funnel-shaped strainer having a removable cup loosely fitted to its lower cylindrical end, the bottom of which cup is perforated, and between which cup and the lower end or neck of the funnel the straining fabric is held and clamped, the cup being provided with a cross-bar or handle by which it is lifted or turned, and having a flanged upper edge which is notched at one point to clear a lug projecting inwardly above the neck of the funnel, beneath which the flanges afterward turn, and which holds the cup rigidly in place by crowding upon the flange and being stopped by one end of the cross-bar or handle.

In the accompanying drawings l igu re 1 is a vertical longitudinal section;

hi 2 is a plan. view of the cup;

Fig. 3 is a View in side elevation of the lat ter showing the gradual rise in the flange which causes the cup to be forced and held securely in place; and

Fig. l is a top plan view of the cover.

A, represents the body of the strainer, the central portion of which has a gradual taper, and the lower end terminating in a cylindrical neck 1, which has an inturned flange 2 at or near the lower end, and a lug 3 projecting inwardly at the upper end of the neck.

C, is a removable cup having a perforated diaphragm l at or near the bottom. This cup is constructed and adapted to fit the in terior of the neck of the strainer, and its lower end is intended to rest upon the inturned flange 2 at the lower end of the neck, and it is provided at the top with outturned flange 5, which rests upon the inclining wall of the funnel part of the strainer just above Specification of Letters Patent.

the neck when in place. This flange 5 is provided with a notch 6 to afford clearance for the lug 3 when the cup is dropped in place. A cross-bar or handle 7 extends across diametrically from one side of the notch (3 to a point opposite on the flange 5 by means oi which the cup .is lifted or inserted or turned axially in the eylindri cal neck of the strainer.

The end of the cross-bar or handle adjacent to the notch forms a stop which strikes the lug 3 and prevents the cup from turning farther in that direction, and the portion of the flange 5 approaching this end of the cross-bar preferably rises gradually like a screw-thread, and by turning beneath the lug it forces the cup down and holds it firmly in place, as is well understood.

Some porous fabric, such as cheese-cloth or Ca11ton-flannel is adapted to be inserted between the neck 1 of the strainer and the cup 0, where it is held taut like a drum- .head over the lower end of the latter, and after clearing the lug by inserting the cup so that the notch 6 is opposite it, the cup may be turned all the way around until the lug strikes the end of the crossbar, and the cup is forced endwise rigidly in place, and tending to apply tension to the fabric and stretch it evenly and smoothly over the end of the cup.

The removable cover 8 is adapted to fit in the upper end of the strainer, and is provided with a swing-lid 9 pivoted at one side thereto, which can be quickly swung aside when the strainer is to be used and swung back in place against the stop 10 to prevent the ingress of dust, dirt, or insects.

In this way, it have provided a simple and inexpensive strainer of few parts, which can be kept clean and sanitary at all times, and the straining parts of which are capable of being renewed and kept cleanly and sanitary.

I claim:

A milk strainer comprising a funnel shaped body portion terminating at one end in a cylindrical neck, the wall portions of which are parallel throughout their entire length, which neck has an inturned flange at or near the lower end, an inwardly projecting lug arranged at the base of the funnelshaped body portion, a removable cylindrical cup having a perforated diaphragm arranged across the lower portion thereof, the

side Walls projecting well below said diaphra-gm, thereby forming a space between the diaphragm and the said inturned flange a notched flange at its upper end, said flange adapted to rest upon said funnel-shaped body portion, a cross-bar extending from one side of the cup to the other and secured to said flange, the notch adapted to receive and clear the lug, said flange arranged spirally so that the opposite edges of the notch 10 therein are in different vertical planes, so that the cup is wedged in place and moved slowly endwise as it turns, whereby to stretch and hold the fabric placed. across the bottom of the cup taut and smooth, parallel 15 with the diaphragm.

In testimony whereof I aflix my signature.
